NEETBotanyPhotosynthesis in Higher Plants
What conclusion can be made about chlorophyll a based on its absorption spectrum?
Options
- AIt is not related to photosynthesis
- BIt is the chief pigment associated with photosynthesis
- CIt absorbs light only in the green region
- DIt reflects all wavelengths of light
Correct answer
B. It is the chief pigment associated with photosynthesis
Step-by-step solution
The wavelengths at which there is maximum absorption by chlorophyll a, i.e., in the blue and the red regions, also shows higher rate of photosynthesis. Hence, we can conclude that chlorophyll a is the chief pigment associated with photosynthesis . Though chlorophyll is the major pigment responsible for trapping light, other thylakoid pigments like chlorophyll b, xanthophylls and carotenoids, which are called accessory pigments, also absorb light and transfer the energy to chlorophyll a. Indeed, they not only enable
